Defence Science and Technology Group (DSTG) provided technology risk assessment advice to the Department of Industry, Science and Resources regarding PsiQuantum's proposal to establish a quantum computing facility in Queensland. The disclosure consists of two ministerial background briefs submitted to the Deputy Prime Minister and Minister for Defence Industry in 2023. DSTG, applying its established authority for technology risk assessment under the 2003 Defence Procurement Review, conducted an independent evaluation of PsiQuantum's photonics-based quantum computer manufacturing process. The briefs note that PsiQuantum, founded in 2016, sought government support for the facility and that DSTG's assessment involved quantum technology subject matter experts including the Chief Defence Scientist. Substantial portions are redacted under various FOI exemptions (sections 33, 47B, 47C, 47E(d), and 47G), obscuring specific technical findings and government deliberations.
